I did that on a NanoPi Neo with the FriendlyARM PCM5102A Hat

( https://www.friendlyarm.com/index.php?route=product/product&product_id=169 )
using kernel 4.14.87-sunxi and armbian 5.67 (or later would be only 5.65?)
(before that I did use legacy kernel 3.4.x with the PCM510A)


and the armbian-BuildSystem

plus (THANKS to) informations in threads from  @dony71 , @Christos, @Valery Rezvyakov
and the the Reference-Threads you could find above :)

cd /home/guido 
dpkg -i ./linux-headers-next-sunxi_5.67_armhf.deb
dpkg -i ./linux-image-next-sunxi_5.67_armhf.deb
(image did include the .ko module for the pcm5102a)

 

----------------------------------------------------------------------------------------------------------------------------------

now REBOOT (on NanoPi Neo)
----------------------------------------------------------------------------------------------------------------------------------

 

=====================================================================================
=====================================================================================
!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ATTENTION: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
After reboot my NanoPi Neo show the following armbian-version:
ARMBIAN 5.65 stable Debian GNU/Linux 9 (stretch) 4.14.84-sunxi
and 2 upgrades for headers&image (without the PCM5102A support)

please keep in mind to freeze the kernel-updates in armbian-config
for not to loose the support (module) for the PCM5120A!
armbian-config -> system -> Freeze Disable kernel upgrades

Yesterday I did read on twitter about a new 4.19.y armbian for the Neo - so I did try that with my PCM5102A-Hat:
 

Quote

Added polished, minimal and top performant #Bionic or #Stretch based images with optimised @linuxfoundation K4.19.y, @armbian hardware configurator and @armbian software installer for @AllwinnerTech #H3 powered #nanopineo https://www.armbian.com/nanopi-neo

 

I did try it like in my instructions above in this thread, but failed (again) with the armbian-add-overlay part.

armbian-add-overlay told me that it cant compile a overlay-dts.

I did found the information that this is because of the missing kernel-headers - the older dtc did told this "secret".

 

OK - I did try to install the kernel-headers via armbian-config -> software, BUT this will not install the kernel-headers for the current kernel-version :(

It will only install the latest available as kernel-header-package.

 

Latest available was 4.14.87 and I did use the new "next" 4.19

 

So I had to use at first the armbian-build-system to create the following .deb's for me :
  

-rw-r--r-- 1 root root   173380 Jan 11 21:43 linux-dtb-next-sunxi_5.70_armhf.deb
-rw-r--r-- 1 root root 10608812 Jan 11 21:43 linux-headers-next-sunxi_5.70_armhf.deb
-rw-r--r-- 1 root root 19933808 Jan 11 21:43 linux-image-next-sunxi_5.70_armhf.deb
-rw-r--r-- 1 root root   171212 Jan 11 20:39 linux-u-boot-next-nanopineo_5.70_armhf.deb

While editing the Kconfig file I did see the name/path has changed

from  

/home/guido/build/cache/sources/linux-mainline/linux-4.14.y/sound/soc/codecs/Kconfig

to  

/home/guido/build/cache/sources/linux-mainline/orange-pi-4.19/sound/soc/codecs/Kconfig

but there was nothing to change because it was already
[EDIT] there was nothing to change, because it was the 2nd compile and the patch was created at the 1st compile.

 

( @dony71 did you also see that there isnt to change anything? I am not sure about the menu-driven screen after selecting m for Module,
  but it did work and create the module) 

config SND_SOC_PCM5102A
    tristate "Texas Instruments PCM5102A CODEC - I2S"

 

After installing the .deb's I hadnt no problem anymore with armbian-add-overlay - because now I had the right kernel-headers for my kernel :)

 

Later I converted the .dtb to .dts, edited the .dts and converted it back to .dtb

 

Now the PCM5102A-Hat is running under

ARMBIAN 5.69 stable Debian GNU/Linux 9 (stretch) 4.19.13-sunxi

Linux npi-neo 4.19.13-sunxi #5.70 SMP Fri Jan 11 21:40:58 +03 2019 armv7l GNU/Linux

 

dmesg|grep -i i2s
  

[    8.524723] asoc-simple-card sound_i2s: pcm5102a-hifi <-> 1c22000.i2s mapping ok

aplay -l

FOR SURE: I did freeze the kernel/updates in armbian-config to keep my PCM5102A working after updating in the future ;)

Around  8 months later I did test my instructions with my NanoPi Neo and 

Debian Buster with Armbian Linux 5.3.3-sunxi <== dev-version
package bsp-kernel[5.98] u-boot[5.98] dtb[5.98] firmware[5.98] config[5.98]

 

Some changes:

 

1.) in the actual armbian-build-system there is no more a ./build/config-default.conf

now you have (after backuping the file) to fill in the content of the attached config-example.conf
to ./build/userpatches/config-example.conf


On my mind I recall there is a symbolic link from ./build/userpatches/config-default.conf
to ./build/userpatches/config-example.conf - so I edited this file ;)

 

2.) for the actual Armbian Linux 5.3.3-sunxi <== dev-version
you have to edit /home/guido/build/cache/sources/linux-mainline/orange-pi-5.3/sound/soc/codecs/Kconfig
( former filenames: 

/home/guido/build/cache/sources/linux-mainline/linux-4.14.y/sound/soc/codecs/Kconfig   OR

/home/guido/build/cache/sources/linux-mainline/orange-pi-4.19/sound/soc/codecs/Kconfig )
 

from 

config SND_SOC_PCM5102A
        tristate

to 

config SND_SOC_PCM5102A
        tristate "Texas Instruments PCM5102A CODEC - I2S"

 

gentle reminder: (because I missed it again while compiling  and had to compile 3 times :( )

when asked about compiling the PCM5102A module press m

Texas Instruments PCM5102A CODEC - I2S (SND_SOC_PCM5102A) [N/m/?] (NEW) m = m for module compilation

 

But with these changes it also does work with kernel 5.3.3 armbian dev debian buster :)

  

Debian Buster with Armbian Linux 5.3.3-sunxi

@guidol should we have an I2S overlay for the H3 boards?  I don't see why not...

Yes ;) a working overlay would be fine if there is also support included for the 5102A in the kernel :)

 

see
  

config SND_SOC_PCM5102A
        tristate "Texas Instruments PCM5102A CODEC - I2S"

above...

Today I tested volumio ( https://volumio.org/ )

Quote

The audiophile music player designed and
fine-tuned for high quality music playback.
Free and Open Source Forever.

on a x86-system and a Raspberry Pi3 and on a webpage I did read that a PCM5102A DAC can be used with the Raspberry Pi (40 Pin header) as a HiFiBerry-DAC.

So I searched how to connect the FriendlyARM (Neo) PCM5102A-Hat to the Raspberry 40-pin header:

the soundcard H3 Audio Codec is only the "normal" analog audio device - not a I2S-audio device.
 

I also got since 5.8.x kernels the problem with a NanoPi A64 that 

1c22c00.codec mapping ok

but I cant get any sound out of the I2S-audio-device.

 

I think its not only a NanoPi Neo problem :( - but when the I2S device like

Karte 1: I2Smaster [I2S-master], Gerät 0: 1c22000.i2s-pcm5102a-hifi pcm5102a-hifi-0 []

doenst show up - then there is another problem in your .dtb/.dts :(

@spender

PCM5102A-Test with Raspberry did end here ;) - so I could test my instructions with armbian buster and Kernel 5.9.0

again on the NanoPi Neo :) 

 

I had only to

- enable (from disabled to okay) i2s@1c22000 in .dtb (decomple and compile) 

decompile:
dtc -I dtb -O dts /boot/dtb/sun8i-h3-nanopi-neo.dtb -o /boot/dtb/sun8i-h3-nanopi-neo.dts

compile:
dtc -I dts -O dtb /boot/dtb/sun8i-h3-nanopi-neo.dts -o /boot/dtb/sun8i-h3-nanopi-neo.dtb

 

- build / addoverlay (  armbian-add-overlay ./sun8i-h3-I2S-out.dts )

- create /etc/asound.conf
[EDIT]
- apt-mark hold linux-dtb-dev-sunxi

- reboot

 

and it works again very well:

According to the method you introduced, the music played happily. thank you very much.  Good good study, day day UP.

@spender for not loosing the .dtb-change (disabled to okay) you also have to set the dtb-package on hold
(here armbian dev example): 

apt-mark hold linux-dtb-dev-sunxi
linux-dtb-dev-sunxi auf Halten gesetzt.

apt-mark showhold
linux-dtb-dev-sunxi

if you are not using dev you could find your dtb-packe with the following command:
root@npi-neo-25(192.168.6.25):~# dpkg -l|grep dtb
linux-dtb-dev-sunxi		20.08.11	armhf	Linux DTB, version 5.9.0-sunxi

Thanks again! There is a new knowledge point! Identified as not modifying dtb.
Now I am trying to add an ILI9341 screen to IT. Since the new kernel no longer supports fbtft_device.ko, it is modified to be defined by DT in dtb. I don't know yet. I am learning how to learn overlay to revise, just like this pcm5102a. If you don’t understand, try to add it yourself. If it is really unclear, I will post for help! enjoy working!

Sorry - Iam not a big specialist in dtb-files. So I cant help you with the display :( 

It could be very difficult/impossible to support the display via dtb when the kernel doenst support it.
But as I remember reading teh forum you did aleready got a own thread for the display (or was it another member of the form)?:

change of .dtb (activating 1c22000) & creating overlay (armbian-add-overlay ./sun8i-h3-I2S-out.dts) does also work on  

uname -a
Linux npi-neo-25 5.10.0-sunxi #trunk SMP Wed Dec 16 17:45:03 +03 2020 armv7l GNU/Linux

package bsp-kernel[21.02.0-trunk] u-boot[21.02.0-trunk] dtb   [21.02.0-trunk]
firmware          [21.02.0-trunk] config[21.02.0-trunk] branch[dev]

like before on kernel 5.9.0 ;)

Instead of manipulating the main device tree, enabling i2s@1c22000 should be possible via overlay as well, like: 

    fragment@0 {
        target-path = "/soc/i2s@1c22000";
        __overlay__ {
            status = "okay";
        };
    };

 

Hence the whole overlay: 

/dts-v1/;
/plugin/;

/ {
    compatible = "allwinner,sun8i-h3";

    fragment@0 {
        target-path = "/soc/i2s@1c22000";
        __overlay__ {
            status = "okay";
        };
    };

    fragment@1 { 
        target-path = "/"; 
        __overlay__ { 
            pcm5102a: pcm5102a {
                #sound-dai-cells = <0>;
                compatible = "ti,pcm5102a";
                pcm510x,format = "i2s";
            };
        };
     };

    fragment@2 {
        target = <&i2s0>;
        __overlay__ {
            status = "okay";
            pinctrl-0 = <&i2s0_pins>;
            sound-dai = <&pcm5102a>;
            pinctrl-names = "default";
        };
    };

    fragment@3 {
        target-path = "/";
        __overlay__ {
            sound_i2s {
                compatible = "simple-audio-card";
                simple-audio-card,name = "I2S-master";
                simple-audio-card,mclk-fs = <256>;
                simple-audio-card,format = "i2s";
                status = "okay";
                simple-audio-card,cpu {
                    sound-dai = <&i2s0>;
                };
                simple-audio-card,codec {
                    sound-dai = <&pcm5102a>;
                };
            };
        };
    };
};


I will verify that the path /soc/i2s@1c22000 is correct, I guess there is a symbol for this as well, but obviously it is not <&i2s0>.

Good afternoon dear Gurus!
I have a Nano Pe Neo Armbian board.
It turned out to output sound to the 5102 chip using your theme.
The question arose how can I output sound in TDM format.
I use the ADAU1452 chip, but I think that this is not important.
As I understand it, you need to correctly register the overlay. but I'm confused. can you please. if it's not difficult, explain how to correctly register the audio settings file for alsa so that I have 4 sound cards in tdm format to output armbian.
thank you very much. Posted in the wrong thread last time. I'm sorry

I may not have written correctly, I would like to transmit several channels on the i2s bus at the same time 6 pcs. As I understand it, you can take any chip that supports multichannel transmission such as front left, right, rear, left right and centre and subwoofer. These chips should just use the method not left justify but tdm
